Veteran with PTSD writes powerful book 'Why is Dad So Mad?' to help explain the disorder to his young daughter.
Army veteran Seth Kastle had everything going for him when he came home from serving 16 years overseas. That's why it was so confusing to him when his life began to fall apart.
He had a job, a loving wife, family, and friends. He knew things would be different when he moved back to Kansas, but he didn't think they'd be that different. But he felt an extreme anger building up inside, a fire inside his chest that he couldn't explain or get rid of.
Kastle was unknowingly suffering from Post Traumatic Stress Disorder (PTSD), an anxiety disorder that can develop after experiencing or witnessing a traumatic event — like war.
